so im making a box for a 15'' L7 i'm running it off 1000 watts the only problem i have is i have no idea how you figure out sub or port displacement? and also i think im going to make it 4 cubes tuned to 40 hz after all the sub/port displacement does this sound good?

Seems a little high tuning wise...You looking for SPL??

According to Kicker.com the L7 15" will work in a 3 to 6 cube ported enclosure. I would tune lower myself, unless you don't listen to music. I would say 34-37 would be better.

I designed a 5 cube net box at 35Hz for a dude and he said it

sounded awsome. But he was using 2 15" L7's (so a 10 cube box)

in and extended cab.

What dimensions you got to work with?

I cannot make cut sheets or drawings.

This one here should work from the free box sticky:

Make sure it will fit in 16" a high box, if so cut the square hole in the middle of the board

on the same side as the port opening.
